I have an OpenLayers map with point clustering, but I want to apply a much finer granularity to the data represented in the map. Specifically, I want to stratify the clusters according to an attribute on the feature (we'll call it 'category').

So, say I have five categories: effectively I need to cluster points only with other points from the same category. I suppose this could be accomplished with five different layers, but this quickly becomes cumbersome as the number of categories gets large (I have 50+ at the moment).

Has anyone seen anything like this with OpenLayers?

Have you checked the dev examples ?

I'm pretty sure you could 'group' them by an attribute. The last example has good info.

    Funny, I had picked through the first two and somehow dismissed the third. This is exactly what I'm looking for. Thanks a lot! Commented Oct 17, 2012 at 16:26
